New prediction methods of the surface tension, density profile and liquid surface layer thickness closed to the vapour-liquid interface based on the gradient theory is proposed in this paper. Refrigerants are considered as research objects. New modification of Peng-Robinson’s cubic equation of state is used by authors in calculation algorithm for surface properties, which doesn’t require information about critical parameters. A new method for calculation of influence parameter is offered. Being carried out verification of methodology for prediction of liquid surface properties shows that the calculated values of surface tension of refrigerants are in agreement with presented in the literature information with enough accuracy for practical applications.

A cogeneration power plant, installation, the apparatuses of which are integrated by gas-air line and water circuit is considered. A mathematical model of CPP statics on the basis of which the algorithm for calculating of the static characteristics of the CPP is proposed. As a result of calculation the scheme of heat distribution generated from the fuel combustion is constructed.

The issues of wineries solid waste analysis as the environmental aspects of the wineries, as well as reducing the burden on the environment through the use of wineries solid wastes as secondary raw material for the new product obtaining are considered. The results of the wineries solid waste analysis as a valuable raw material for feed additive obtaining are given. It is proved that the dominant substance of marc and crests chemical composition are carbohydrates, namely cellulose.
